"We put our economic impact at $4 million," said director of the Sacramento Sports Commission Mike Sophia.
The financial impact estimates are based on the needs of both riders and fans, including hotels, food and miscellaneous purchases.
The recent NCAA Men's Basketball Tournament, which saw opening round games at the Golden 1 Center, was estimated to bring in more than $5 million in economic impact to the Sacramento area. However, the Amgen Tour of California is a little harder to predict.
"We knew with the basketball tournament there would be 17,000 fans at each game, there could be 30,000 fans for the cycling races, but it's a big area and hard to tell," Sophia said.
At the Mike's Bikes location in midtown Sacramento, staff anticipate an uptick in customers following this weekend's racing.
"After the race people start thinking they need to upgrade some stuff, so we'll start seeing some more road bike sales and also in clothing too," says assistant manager Andrew Van Tassel.
